To all whom it may concern.'

Be it known that i, CHESTER A. Massari., a citizen of the United States, residing at East Madison, in the county of Somerset and State of Maine, have invented certain new and useful Improvements in Power-Gages and Lug- StrapsforLooins, oi' which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in looms, and particularly to a power gage and lug strap therefor.

The object of the invention is the provision of means for facilitating the transmission of power of increasing force to the picker stick during each forward movement of the same, for causing the shuttle to travel through a shed of warp.

With this and other objects in view, the invention consists of certainother novel constructions, combinations, and arrangements of parts, as will be hereinafter hilly described and claimed.

In the drawings: Figure 1 is a view in side elevation of a device constructed in accord ance with the present invention. Fig. 2 is a yerspective view of my improved lug strap. ig. 3 is a top plan view of my lug strap attached to one end of a sweep stick. Fig. 4 is a perspective view of the stud-plate. Fig. 5 is a vertical, sectional view taken on line 5, 5, Fig. 1. Fig. 6 is a vertical, sectional -view i taken on line 6, 6, Fig. 1.

Referring to the drawings by reference numerals, 1 designates the sweep-stick, through the medium of which movement is imparted to the picker-stick 2. The sweep-stick is connected to the picker-stick by means ot my improved lug strap 3. It is desirable to adjust the position of the lug strap with respent to the-picker-stick for throwing the s iuttle with more or less velocity, and this is accomplished through the medium of my sectional power gage li, hereinafter specifically described. The adjustment of the lug strap 3 up 01 away "from stud-plate 6, upon which the picker-stick 2 is supported, applies less power to the shuttle, and if the lug strap 3 is moved downward or towards studplate 6, the power applied to the shuttle is increased. As the specific structure of the swee -stiok 1 and the picker-stick 2 is imm ateria so far as my invention is concerned, it will be -understood that any structure known to the 'prior art may be employed in constructing a device in accordance with my invention.

The stud-plate 6 is provided With a square aperture 7, preiera ly formed centrally therein, and said plate is provided With studs 8, S extending from one side thereof. These studs are preferably formed vintegrally with' stud-plate 6. Each stud 8 is provided with an aperture 9. VJithin the apertures 9 of the studs S, suitable spring cotters 1U are ositioned 'for securing the picker stick 2 an( the power gage 4. upon the said stud-plate 6. The stud-plate 6 is adjustably secured in a horizontal position upon the supporting arm 11 of the loom by means of a bolt 12, which is provided with a shank square in cross-section, so that when the shank is positioned in the square aperture 7 and the elongated aper ture 13 of the supporting' arni 11, rotary movement will be prevented, and consequent-ly the stud-plate 6 Will be held in horizontaL-parallel position with the supporting arm 1 1. By means of the apertures 7 and 13 and bolt 12, the studlate 6 and the supporting arm 11 are eiectually secured together when the nut 14 is tightened upon said holt.

The picker-stick 2 is held in its normal position through the medium of an ordinary strap 15 and a spring 16; the spring 16 being adjustably secured at one end to the strap 15 andat its opposite end to any suitable sup port or part of a loom.

The substantially U-shaped strap 3 is pref-- erably formed oi flexible material, as 'for instance, leather, and is cut from a single or a plurality of pieces of material and folded over for placing the ends in substantially parallel position, Figs. 2 and 3. It `is immaterial,-so tar as the nature of the invention is concerned, whether the lug strap is made from a single piece, oi a plurality of pieces, the pieces being secured together in parallel position. The lug strap 3 is provided with depending ears 17. In each ear there is formed a horizontally extending, elongated aperture 18. .Upon each side of the lug strap 3, and near the upper, horizontal edge theref of, there is formed an aperture 19. By reason of the peculiarstructure ot my 'folded strap, a very efficient device is produced.

Through the action of' the lug,` strap traveling downward upon the picker stick, and at the same time traveling forward during the pick of the loom, and also necessarily very tightly hugging the picker-stick, it can be where it is fastened to sweep stick 1.

seen that the old, straight lug strap would very quickly ramp upward from the' pointl To overcome this fault, it is necessary, to get a perfect picking loom, to have the lug strap ot some sott or llexble material, yet strong enough to pertorn'i the work, and as heretofore stated, l. preferably use leather, 'for it has been found to be more suited to this' worli than any other material.

By the shape and construction ot my lug strap, l have overcome the tendency i cramping upward, as the width between the sides ol my lug strapvaries (see Figs. 2 and 3) from the irontends or point ot Fastening to power fl and sweep stick 1, tapering to the outer, curved or rounded end 20, thus forming a brace lor said end, holding it downward in its correct position which is in a straight line with the top ol sweep stir-h. Fru'therlnore, the tapering structure ol" the strap, see Fig. I3, obviates the liability of the formed in the sweep stick l, and the aperturcs 1S) of the lugstrap 3. Of course, it will be obvious that the apertures 1l) register with the aperture ot the' sweep stick, and l-preterably position washers22, 22 upon bo'lt .19 against the outer surfaces ot the lug,l stra 3 against whichwashersthe head 23 ot lthe. bolt and nut 24 are positioned.

The power. 4 comprises an upper, bi-

turcated member 25 and a lower, bit'ureated e member 26. An intermediate member 27 connects the upper and "lower members 25 and 26. The upper, bifurcated member 25 is positioned between the depending ears 17, 17 ot the lug strap 3. The bolt 28 is positioned. within the elongated apertures 18, 1S ofthe ears 17, 17 ot the lug strap 3, and upon said bolt, a'sleeve 2i) is mounted between the ears 17, 17. Washers ISU, ll are positioned upon the bolt 2t; against. the inner surfaces of the -depending 'ears 17. The ends ot' vthe sleeve 29 abut against the washers 30, 30. Positioned upon the bolt 2S and against the outside ol the depending ears 17, are washers 31, K1. An ordinary. nut 32 is threaded upon the bolt for securing the parts in their assembled position.

The lower, bifurcated member 26 is provided with an aperture 33, within. which is positioned one of the studs S, whereby the power gage pivot-ally mounted 'uponthc sind-plate 6. The intermediate member 27 is prel'erably liormedof a llaibar and is provided with an upper aperture in which any suitable fastening nuans, as bolt Si, is posi- `tioned for securing the upper end of said member 27 within the bil'urcated portion 35,

Fig.. 5, of the upper, bifurcated member 25.

lThe upper, bifurcated member 25 is provided with apertures registering with the aperture formed in the upper portion of the intermediate member 27, through which the bolt 34 extends.- Theintermediate member 27 is provided with an elongated aperture 36 formed near its lower end. The lower, biturcated member 26 is provided with registering apertures 37, Fig. 6, similar to the upper, bil'urcated member 25, within which apertures B7, any suitable fastening means, as for instance, bolt 38,' is positioned for securing the intermediate nrember-27 in an adjusted position. This fastening or holding ofthe intermediate member 27 in an adjusted position with respect to the lower, bifurcated member 26, is accomplished by reason of the tact that the material of which the lower, bifurcated member is formed is of sutlieient resiliency to clamp the intermediate member when the nut 39 is threaded upon the bolt 38. I havef'ound trom actual experience that by? tightening the nut 39 upon the bolt, the outerC will holdvthe intermediate member in any adjusted position between the bifurcated portions of said member 26. I preferably form the upper, bifureated member 25 of stiif leather, While vthe lower, bifureated member 26 is preferably formed of Wood, or any analogous material. By looseningI nut 39, d the lug strap maybe adjusted longitudinally upony the picker stick 2, and subsequently nut 29 may be threaded upon the bolt 38 and the lug strap will thereby be held in its` adjusted positie A .l have'found from experience that the lower portion of the power gage 4 should always be yin the 'same relative position With respect to the picker stick 2, lche top thereof should be made slightly adjustable towards or away from the picker stick, and to provide for this slight adjustment, I have formed the elongated slots or apertures 18 in the depending ears 17 of the lug strap 8. The object in adjusting top of power gaffe is to alter its relative position to the picokerstick regardless of the position of the pieken stick. By this ad'justability ofthe upperend ot the power gage, the lug strap can be caused to move downward to amore or less extent during the pick o l the loom, thus securing a hard or a light pickf as is desired. f The alteration or adjustment of the upperend of the power gage 4 need only be very slight to secure desired results.

The depending ears of lugs 17o my lug strap reinforce and strengthen t e entire strap, besides constituting a brace for the i rear nd 20 nl." said strap. Furthermere, by employing the depending ears, :llexi le ma l terial may be employed in constructing the ends ot' the bifurcated portions of member 26 a lug strap carried by said sweep-stick and in porting arm, and a sweep-stick, said sup porting arm provided with an elongated apstrap, which is very desirable, as a flerble strap Works far better than a metallic strap. Another advantage of my depending ears or erture, of a studeplate in engagement With lugs lies in the fact that the power-gage is l said supporting arm, said stud-plate provided connected beneath and contiguous to the with a squared aperture and with laterally sweep-stick l, Which leaves the rear portion I extending studs, fastening means positioned of my strap free, and, therefore, only neees- I within the squared aperture of said studsitates the strap to he of suflieient length to g plate and Within the elongated aperture of allow the movement of the picker-stick 2 l said supporting arm for securing said plate therein, and to surround said stick. l upon said arm, a picker-stick mounted upon l/Vhat I claimis: one or` said studs,'a lug strap secured to said l.
